Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure of wall panels which are vertically connected to each other to construct a side wall of an assembled bathroom called a unit bath.

[0002]

2. Description of the Related Art Conventionally, a side wall of a unit bath or the like has been formed by vertically arranging wall panels that are long in the vertical direction and standing on a floor pan. However, in such a method, since the height from the floor pan to the ceiling is determined by the height of the wall panel, there is a problem that the ceiling height cannot be selected according to the construction site.
Further, since the height of the wall panel is long from the floor pan to the ceiling, there is a problem that a plurality of workers are required for assembling the side wall and the assembling work cost becomes high. .

In order to solve such a problem, there has already been proposed a method in which a plurality of wall panels 101 are vertically connected to construct a side wall 102 as shown in FIGS. -105584, etc.). That is, according to this method, the height from the floor pan to the ceiling can be freely adjusted by adjusting the number of wall panels 101 connected in the vertical direction, and the wall panel 101 can be downsized. The advantage is that the assembly workability is also improved.

In FIGS. 5 and 6, reference numeral 104 is a corner metal fitting, and 105 is an engaging projection, which is engaged with an engaging hole provided in an upper wall panel 101 (not shown) to form upper and lower walls. The position of the panel 101 can be regulated.

However, the method of connecting the upper and lower wall panels to construct the side wall has the following problems. That is, in the conventional method of connecting the left and right wall panels to construct the side wall, when a part of the wall panel is cut out and the window opening is provided in the side wall, the vertical direction of the side wall is one wall panel. Therefore, even if a load is applied to the side wall from above the window opening, it has sufficient strength to withstand this load.
In the method of constructing the side wall 102 by connecting the wall panels 101 in the vertical direction as shown in FIG. 5, the contact surface between the upper and lower wall panels 101, 101 is reduced in the portion where the window opening 103 is provided, and the force in the arrow direction is reduced. It cannot exert sufficient strength when added.

In particular, as shown in FIG. 6, when three or more wall panels 101 are vertically connected and a window opening 103 is provided over the three wall panels 101, the middle wall panel 101 is divided at the center. Therefore, the original strength of the panel cannot be maintained. In view of such circumstances, the present invention provides a structure in which the upper and lower wall panels are connected to each other even when the wall panels are connected in the vertical direction to construct the side walls and the window openings extending over the upper and lower wall panels are provided in the side walls. It is an object of the present invention to provide a wall panel connection structure that can be firmly connected to obtain a solid side wall.

[0007]

In order to achieve such an object, the present invention provides a wall panel connection structure for constructing wall surfaces by connecting them in the vertical direction, in which the vertically adjacent wall panels are Reinforcing members are provided on the back side along the joint ends, respectively, and two adjacent reinforcing members have through holes through which threaded portions of bolts can be inserted at corresponding portions, and the cross-sectional shape is substantially the same. A screw receiver having a U-shape and a U-shaped horizontal piece provided with a screw hole to be screwed into the threaded portion, and a notch capable of inserting the threaded portion at a portion of the other horizontal piece facing the threaded hole. The metal fitting is inserted into one of the reinforcing members so that the horizontal piece on the side provided with the notch is inserted between the two reinforcing members, and the screw hole and the notch are aligned with the through hole. The bolt goes from the other reinforcement member to the one reinforcement member. It is through the through hole and notch I,
The two reinforcing members are sandwiched between the bolt head and the screw receiving fitting by receiving the bolt head on the other reinforcing member and screwing the screw portion into the screw hole.

[0008]

According to the above structure, before or after the upper wall panel is placed on the lower wall panel, one of the reinforcing members of the upper wall panel and the lower wall panel facing each other in the vertical direction can be used. Fit and set the screw receiving bracket in the specified position. Then, by inserting the bolt from the other reinforcing member side through the through hole and the notch to screw the screw part of the bolt into the screw hole of the screw receiving fitting, the bolt head received by the other reinforcing member and the bolt receiving part. Two reinforcing members are firmly sandwiched between the metal fittings. That is, the upper and lower wall panels are firmly fixed by sandwiching the two reinforcing members.
